Abstract

This work presents heartbeat and respiration detection sensor to be applied for mobile communication devices. To estimate the near field effect, simulations are proceed to observe the magnitude variation of antenna reflection coefficient induced by human thorax movement of heart and lung. Experiments are carried out for heartbeat detection using dipole antenna with coupler and a method to improve the sensitivity of the system is proposed. Proposed cardiopulmonary detection system is implemented with off-the-shelf components at 2.4 GHz and excellent performance is obtained.
